Why Backflow Prevention Is Often Required, Not Optional
Backflow prevention devices stop contaminated water from flowing backward into your home’s clean water supply, a risk that can happen during pressure changes like a water main break or heavy usage nearby. Many jurisdictions require annual testing of these devices, especially for homes with irrigation systems, pools, or certain plumbing configurations.
Backflow prevention exists for the one time pressure drops the wrong way, and it matters that it works that one time.
When Backflow Service Comes Up
These situations are common reasons homeowners need this service.
- Your city or water utility requires annual backflow device testing
- You have an irrigation system that requires a backflow preventer
- You’re installing a pool or other system that needs backflow protection
- Your existing backflow device failed a previous test
- You’re buying or selling a home and backflow compliance was flagged
What to Prepare Before Requesting Backflow Service
Testing must be done by a certified professional, but a little prep helps.
- Check with your local water utility on your specific testing requirements and deadlines
- Locate your existing backflow device if you have one, often near where irrigation lines connect
- Keep records of past testing, some jurisdictions require submission of results
- Ask whether the plumber is certified to perform backflow testing in your specific city
